It was a walk-in process in which approximately 900 candidates were called. The first round was an aptitude round in which they selected near about 200-300 candidates.I was lucky to be one of them. The second round was a GD round in which a batch of 10 students was selected.I cleared the GD round as well. The next round was the technical round in which the interviewer asked me about my final year project ,some basics about my skills and few HR questions. After that, the day was over and the organizing team asked everyone to leave for the day and the told that the results will be declared in a week. I was confident for my selection. After a week 48 students were sent a mail for document submission and I was one of them. After the documents were submitted the HR called me after a week for final confirmation of selection and told about the package offered and joining date and I will receive my offer letter in a day or two. Me and my family were happy about the results. 2 days were over and I didn't receive my offer letter so I called the HR and she told that they are not selecting people who have an year gap(gap after 12th or year down) or who had over qualifications(10+2+3(diploma)+4(degree)) and offered the job to those who ranked below us. .Please note that these criteria were not mentioned before the interview. Like me, there were few more candidates those were depressed about this result and that too after waiting for almost a month. One of the worst experience of my life.HR operations in Tieto do not feel the emotions of a candidate. I would request the HR's to verify everything before confirming. Thank You.
